Application July 28, 1955, Serial No. 525,018

7 Claims. (Cl. 114-208) My invention relates to a new and useful improvement in an anchor used for anchoring boats.

Experience has shown that it is a common objectionable feature that an anchor having wings or arms projecting outwardly from the lower end of the anchor frequently become lodged on rocks or other obstructions at the bed of the stream or body of water. This is particularly the case when the boat drifts, dragging the anchor along the bottom. Frequently, because it is impossible to dislodge the anchor from the obstruction on which it has become connected, it is necessary to cut the anchor line and thus the anchor is lost to the user.

Another objectionable feature with an anchor having outwardly projecting fixed parts at the anchoring end is that it is difiicult to transport or carry the anchor from place to place.

It is an object of the present invention to provide an anchor having anchoring win-gs or arms extending outwardly from the anchoring end so arranged and con structed that they may be readily and easily collapsed outwardly from the supporting body so as to extend substantially parallel thereto and thus permit the anchor to be easily removed from obstructing material on which it may have become engaged.

Another object of the invention is the provision of an anchor having swingable anchoring parts which may be folded to lie substantially parallel to the supporting body so that the anchor thus may be easily transported and will occupy a minimum amount of space.

Another object of the invention is the provision in an anchor of a trip mechanism whereby the anchoring parts may be easily and quickly tripped to move from operative to inoperative position.

Another object of the invention is a mechanism for retaining the anchoring parts in anchoring position and of a mechanism for retaining the anchoring parts in folded position.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made in the detail of the structure illustrated without departing from the invention and it is intended that the present disclosure shall be considered to be but the preferred embodiment.

Fig. 11 is a fragmentary end elevational view showing the parts in the position indicated in Fig. 1;

Fig. 12 is an end elevational view showing the parts in the position shown in Fig. 2.

As shown in the drawings, the invention comprises a tubular housing 17 having its upper end enclosed by an inverted cup-shaped member 18 provided with the inwardly projecting flange 19 at its open lower end and having an opening 20 formed through the upper flange which forms the top side of the supporting portion of the anchor.

Projecting through this opening 20 is the anchoring rod 21 having an eyelet 22 to which a suitable usual anchor cable or rope may be attached. This rod 21 passes through a collar 23, the rod forming a snug fit as it projects through the collar 23. This collar 23 is provided on its upper end with the outwardly projecting flange 24 which serves to engage one end of a coil spring 25, the positioning end of which bears against the flange 19. The spring 25 normally tends to retain the rod 21 centered relatively to the tube 17.

Mounted on and projecting inwardly of the lower end of the tube 17 is a carrier or supporting body 26 which is formed generally cup-shaped with the closed end 27 positioned upwardly and having a hub 28 projecting outwardly therefrom. Extending through this hub 28 and the closed end 27 is a passage 29 through which slidably projects, in snug relation, a rod 30. This rod 30 is provided at its lower end with a plunger or head 31 which slidably engages in the bore 32 of the member 26.

A coil spring 33 engages at one end the lower face of the closed end 27 of the supporting body 26 and at the bottom end the upper face of the head or plunger 31 so as to normally tend to move the plunger or head 31 downwardly. When this plunger or head is moved downwardly a sufiicient distance, the rod 21 will be moved into alignment with the rod 30 and these two rods will engage each other at their opposed ends. When in such engagement the rod 30 can then not be moved upwardly against the compression of the spring 33. When the parts are indisengaged position, 'as shown in Fig. 10, the rod 30 can be moved upwardly against the compression of the spring 33.

Pivotally mounted on the supporting body 26 by means of pivot pins 34 are three supports 35 on each of which is fixedly secured a leaf or wing 36 to provide anchoring arms which, when in the extended position shown in Fig. 2, serve as 'a means for anchoring a boat or the like. When in the extended and operative position shown in Fig. 2, these anchoring arms will engage the bottom of the stream or lake and embed themselves in the bottom or lodge themselves against the obstructions on the bottom, affording an effective anchoring mechanism.

Extending outwardly from two of these supports 35 is a tongue generally designated by the numeral 37 and the third support 35 is provided with a similar tongue 38. The tongue 38, as clearly shown in Fig. 11, is longer than the tongues 37. When the anchoring arms are folded into inoperative position, as shown in Fig. l, and also in Fig. 4, the tongues 37, and likewise tongue 38, engage the bottom face of the plunger or head 31, and due to the pressure of the spring 33, these anchoring arms are held in collapsed position. i

When it is desired to move these anchoring arms from the collapsed to the operative position, i. e. from the position shown in Figs. 1 and 4 to the position shown in Figs. 2 and 5, it is but necessary to swing the parts 36 downwardly from a position shown in Fig. l or Fig. 4, and in this downward swing the tongues 37 and 33 will move the plunger or head upwardly against the compression of the spring until these tongues 37 clear the periphery of the head or plunger 31, whereupon the tongues will move into the position shown in Fig. 2 and Fig. 5. The tongues 37 and 38 then lie in engagement with the periphery of the head or plunger 31.

Formed on each of these supports 35 is a nose 39 which engages the lower end of the plunger or head 31 so that these anchoring arms embodying the members 36 are held in a rigid operative position relative to the remainder of the structure. Thus the anchoring arms are held rigidly in the position shown in Fig. 5.

When an obstruction or other impediment is met on which the anchoring arms lodge, while the boat is drifting or being propelled, the arm or member 36 which is engaged will serve as an impediment for further travel or drifting of the boat. The operator then, by pulling on the usual anchor cable fixed to the eyelet 22 may rock the rod 21 into the position shown in Fig. 6, whereupon the member 36 which is engaged will rock downwardly, as shown in Fig. 6, moving the head 31 upwardly, and upon this downward rocking the remainder of the members 36 will fall into the position shown in Fig. 3, thus permitting the clearance of the obstacle which has caused the undesired engagement.

When this undesired obstacle has been cleared, a downward pressure on the members 36 will, through engagement of the inclined or beveled surface 40 which engages the terminal inclined surface 41 of the plunger or head 31, again be rocked upwardly, through the pressure of the head or plunger 31 against this inclined surface 40 into the operative position shown in Fig. 5 and in Fig. 2. Consequently, the anchor will automatically arrange itself into the position shown in Fig. 3 and in Fig. 6 for disengagement with a stationary object against which it has been lodged and thus it is cleared from such object.

After use of the anchor, when it is desired to move the anchor arms into the position shown in Fig. l and in Fig. 4, the rod 21 would be tilted into the position shown in Fig. 6 and the anchoring arm having the longer tongue 38 would be rocked downwardly from the position shown in Fig. 5 until the nose 39 on this arm has moved the head or plunger 31 upwardly of Fig. 5 a sufficient distance to clear the tongues 37, whereupon these anchoring arms carrying the tongues 37 could be moved into the position shown in Fig. 1 and Fig. 4.

In this movement, the arm or support 35 carrying the longer tongue 38 is rocked to force the head 31 upwardly of the bore 32. As shown in the drawings, there are three of these anchoring arms used and in this movement the two anchoring arms having the shorter tongues 37 will be released for folding into the position shown in Fig. 4 and Fig. 1.

It will be noted that in the position shown in Fig. 5 and Fig. 2, the nose 39 is in engagement with the bottom surface 41 of the plunger or head 31. After the two anchoring arms having the shorter tongues 37 have been folded upwardly, in order to release the anchoring arm having the longer tongue 38, it is necessary that the plunger or head 31 be moved upwardly by the nose 39 of one of the other arms having a shorter tongue 37 until the tongue 38 is released.

We have a situation then where the longer tongue 38 engages the bottom of the head or plunger 31 and by swinging the anchoring arm carrying the tongue 38 downwardly, the plunger or head 31 may be moved upwardly sufiiciently to disengage the tongues 37 on the other anchoring arms and thus the three anchoring arms are 4 folded into the position shown in Fig. 1 and Fig. 4 and are held in this position due to the pressure of the bottom surface 41 of the head or plunger 31 against the tongues 37 and 38, the spring 33 functioning to supply sufficient pressure.

In this manner I have provided an anchor which avoids the disandvantages referred to herein and which is possessed of the advantages mentioned, while at the same time, a structure which is economical of manufacture, durable, compact, highly efficient in use and easily and quickly moved to various positions of use is provided.
